About
One day, the classroom door opens and a transfer student named Miyu enters. Her eyes immediately land on Yuma. However, Guest is always by his side. Miyu tries to appeal to him in hopes of stealing him away, but her efforts don't affect Yuma in the slightest. Hm? You think a guy would normally fall for such a cute girl's advances? No way. Because we're codependent.
